VEHICLE-WHEEL.

Specification of Letters Patent.

Patented July 28, 1908i Application :Bled June 10,1907.. Serial No. 375,054. v

To l@Uw/1,0m 'it may' concern: c Be' it known that I, HARRY M. MARTIN, citizen ofthe United States, r esiding at Columbus, in the county of Franklin and State of Ohio, have invented" certain new andrusef' ful Im rovements inVehicle-Wheels of which the fo owing is a'specification.

My invention relates to vehicle wheels and hasfor its object the provision of a device of this character, which whilepossessing all the resiliency of the Ordinary pneumatlc tired 'v supplementary rim and the means for securing it in position upon the Wheel, thatl the wheel, will 1s secured.

P riphery 11.

p res'ent a puncture-proof surface to the road ed. 4 i A further object ofthe invention is the rovision of a su plemental rim which may e readily applic at a very small cost, to the vehicle whee s which are already in use and which ,will render said wheels puncture roof.

Further objects and advantages of t e invention will be set forth in the detailed description which now follows.

In the accompanying drawin Figure 1 is a side' elevation of -an automobile wheel having my improvements applied thereto, Fig. 2 is a transversesection of a ortion of said wheel and of the su plementa rim upon line m of Fig. 1, and, 1g.-3'is a detail perspective view o'f'one of the saddles hereinafter described. f

Like numerals designate corresponding parts in`all of the igures'of the drawing.

Referring to the drawing, the numeral '5. designates the hub of an `ordinary automo` 'bile wheel; radiating from4 this hub are the spokes -'which'carry the usual rim 7 to which av pneumatic tire 8 of ordinary construction -The wheel just describedis of the usualand wellknown construction and forms no part of the present invention. It is inthe present invention particularly resides. The

'supplementary rim 9 carries a solid 'tire 10 vwhich is preferably formed of rubber.

supplementary rim has a V-shaiped inner -peof sa A plurality V-shaped bases 13 whic enga e with the inner periphery ofl the supp emental rim.

These sa dles are recessed as at 14 for the rece'ption of the periphery of thetire 8', said recessed ortions being rounded as at 15 to Vprevent t e cutting ofthe tire.

12 may be-forined of wood, rubberor leather g This dles 12 have,

The saddlesas is found'to be bestsuited. The provision of the rim havin a V-shapedinner periphery `and of the sadd es having V-shape recesses which engage said rim, provides' a structure which' prevents the wheel proper from vb'eing .forced out of the supplementary rim when passingaround corners. Y v

' It will be apparent that the present invention is a very simple one and provides a structure -Which maybe readily a plied to the automobile wheels whichare a ready in use, at a very small`cost.

In applying this rim, it is but necessary to deiiate the tire S and to place the outer or supplementary rim and the saddles in position. After this has been done, the inflation there is a tendency for the wheel to skid in ofthe tire 8 will lock all of the parts securely together.

While the elements shown and described are well adapted to serve the purposes for ing the pneumatic tire and supporting said supplemental rim.

2 The combination with a vehicle wheel having a---pneumatic tire, of a sup lemental rim having a Vrsha ed inner perip ery,A and aplurality of saddles engaging-the pneumatic tire and the V-shaped periphery of the supplementalrim. v

3. The combination with a vehicle'rim havin a'pneumatic tirethereon, of a supplementa rim which encircles-said*pneumaticv tire, and saddles which space said supplementary rim from said ti`re, said saddles ave ing V-shaped recesses formed therein, and l v said ,supplementary rim having a -V-shaped inner periphery-with which said .saddles ena e.-` g n testimony whereof I aflix my signature yin presence of two witnesses. f
